[Car Show] I changed the transmission oil from Aisin’s original factory. I didn’t expect this result
GeorgeBecher 
12 Xiao 7’s gearbox is Aixin’s 8AT, and the manual says “maintenance-free”. After buying a car, there are a lot of videos on the Internet about whether or not to change the gearbox oil for maintenance-free gearboxes. In my opinion, the so-called “life” actually has a time limit. On average, the “life” of each car in the hands of a car owner is estimated to be only four or five years. Considering that Xiao 7 may stay in my hands for a long time, I think it is still necessary to maintain this area on a daily basis, and there is no need to do so much. My friend also suggested that I usually change the gearbox oil for about 60,000 kilometers, but it is not good for the gearbox to wait too long. To be on the safe side, I found an meized outlet that could be found by Aixin officials to change the gearbox oil.
After all, Xiao 7 was too small, and there were some twists and turns in the process of changing the gearbox oil, but the result was good. The gearbox oil was changed smoothly, and by the way, there was a wave of antifreeze.
This time I came to change the gearbox oil as a routine maintenance, but as a result, the gearbox oil was changed, at least temporarily solving a stubborn problem of Xiao 7. Xiao 7 has the problem of changing gears when it is new, especially when changing gears from 2 to 3, many cars have this problem. My Xiao 7 has improved a lot after upgrading the gearbox program, but with the passage of time, the setback has become serious again, and I have actually got used to it for so few years. As a result, as soon as the gearbox oil was changed, the frustration was directly “gone”. I didn’t believe it myself, and I felt it carefully for a long time, but I really didn’t feel it. Under the energy-saving mode with the most serious setback in the past, now the sudden setback is only occasional and very soft. It really surprised me.
Can a change of transmission oil still do this? After thinking about it, it may be because the gearbox oil has not been replaced for a long time, the performance of the original oil has declined, resulting in increased gear wear inside the gearbox, and the impurities produced are easy to block the oil channel, which leads to the problem of vehicle frustration. The gearbox oil generally has three major functions, including power transfer, lubrication and heat dissipation, as well as anti-corrosion, anti-rust and cleaning functions. The gearbox is like the “heart”, injected with new blood, the blood vessels everywhere are open, and the problem of frustration is easily solved. This is the only way I can understand it. I welcome those who know how to correct it. But now it seems that if there is a setback in your car gearbox, and it is more serious than before, it may be an effective solution to change the gearbox oil.
So here comes the question again. How long will it take to change the gearbox oil? I don’t know about that. There’s everything you can say on the Internet. This time, the posters posted in the store suggest a change of 2 years or 40-60,000 kilometers. Since this time it is 60-70,000 kilometers, I intend to change it according to the cycle of the store next time.
Next, let’s pick up the whole process of changing the gearbox oil.
Before going out, I recorded the current mileage of the car, 67475, but I didn’t see 66666. I was sad.
I slipped to the door of the store half an hour ahead of time, which was much faster than I thought.
At the time of arrival, the shop was still eating, but fortunately, there was only one car in front of me to repair the tire, which did not delay me to change the gearbox oil. Aixin’s exclusive parking space was arranged.
So which car gearboxes for Aixin can be seen on this table, that is, this watch is a little old, and there are certainly no new cars in the past two years. But this Japanese and Korean, there are no Korean cars, ah, ha.
French car has always been a loyal user of Aixin, from 4AT to 6AT to 8AT, always love Xin, it is supposed to make Aixin gearbox perfect, how can DS get on the shelves and make DS7 like this in China.
Upper lift
By the way, I took a look at the engine compartment. Last time, 4S rushed to change the valve cover for Xiao 7. Originally, I thought the oil leakage was not serious and I didn’t want to change it, but it was OK to repair the air conditioner. There were no obvious traces of oil leakage under the new valve cover.
Come to watch Xiao 7’s chassis again, it is still very regular, and the protection is also in place. Here the fuel tank is wrapped by the guard plate, so we can see that there are still obvious scars on the guard plate.
This is the first time for me to take a closer look at Xiao 7 when he removes the engine guard.
The silver part on this side of the exhaust pipe is the gearbox, the volume is very compact, can you think of this there are eight blocks, I remember that the gearbox should be a big one.
Let out the old gearbox oil before changing the oil. If you release the old gearbox oil, you can see that the color is completely black.
Patiently drain oil ing
When the flow rate is low, it will be opened.
After opening it, continue to drain the oil and keep it as clean as possible.
The circulation machine was pushed out.
The new unopened gearbox oil is also in place.
Yeah, and then it was opened.
As a result, I ran into trouble and could not find a suitable circulation machine interface for DS7.
The oil discharge interface of DS7 does not fit with the existing interface. The boss asked for someone to borrow it, and he did not get a suitable one for coordination with the manufacturer. This is very embarrassing, ah, and he still suffered from the loss of minority cars. But fortunately, the recycling machine can not be put, but also can be replaced by gravity, after all, it can be changed. The boss said that the next time you need to change the gearbox oil, contact him in advance to open the mold to customize an interface, you must like it.
The boss still struggled for a while, tried a lot of other interfaces to see if it could work, after all, the recycling machine was still cleaner, but it didn’t work.
No matter how the oil is released, it’s time to add new oil. Look at the fresh red oil. It’s like injecting fresh blood into the car.
After filling up the oil and testing it, it is finally done.
The gearbox oil is done, and then watch the boss continue to change the coolant and shake the cat by the way.
The coolant should also be replaced by circulating equipment to ensure that air is not mixed into the pipeline.
Since you change the gearbox oil here in the Aixin meized store, if you want to change the antifreeze, you will naturally choose Aixin. According to the boss, Aixin antifreeze is an organic coolant containing OAT, which has strong anticorrosive ability, long life, meets Chinese / Japanese / European and American standards, and is suitable for all kinds of models, unlike many refrigerants on the market that only meet the national standard.
The color is more magical than transmission oil, red and glowing. It usually looks like a dark red coolant in the kettle. Is the body so dreamy?
After the thorough completion, the boss also cleaned very carefully, the feeling is full, I expected that there is no cleaning this link.
This is the gearbox oil I used this time, AFW6. At first, when I took this gearbox oil and looked at it, I was shocked. I saw that the instructions on the package said it was for 6AT. At that time, my heart skipped a beat. Didn’t the store give me the wrong model?
Mainly I saw that there were AFW6 + and AFW8 models in this series on the poster in the store. Doesn’t this seem more like the transmission fluid used in 8AT? I panicked even more
However, Aisin’s official Weibo is doing a good job. Adaptation information can be found directly on it, so I feel relieved. The gearbox oil adapted to the DS7 is AFW6, which is originally Aisin’s gearbox. This cannot be wrong. This is not bad, and it also avoids the situation of asymmetric information being deceived
You can also check the specific information of this oil above
Anti-counterfeiting can also be checked. I took a random bottle and looked at it, and it was indeed authentic. Logically speaking, I should scan every bottle, but I’m really too lazy to do this… I often hear that it’s difficult to distinguish between the real and fake oil when buying oil online. If everyone could check the authenticity so intuitively, it would be much better.
I also swept the antifreeze, and naturally it is also genuine.
After changing the oil, I tried both manual mode and energy-saving mode, and the effect was excellent.
It had been many days since I finished writing the post. It was not an illusion that the frustration had “disappeared”. It was a good maintenance experience!
